SYSTEM PROVIDING FREEZE OF CLOSED CAPTIONING DATA

摘要

A video signal processing system produces an output signal suitable for producing a closed caption display and is responsive to a "freeze" command from a user for modifying generation of the output signal such that the content of the closed caption region of the display does not change. The system provides for user selection of various freeze modes including one in which just the caption region of a display is frozen, another in which just the video region of the display is frozen, and another in which both the caption and video regions of the display are frozen.
